The reaction of cows to a short-term deprivation of lying

Abstract

In a herd of 20 cows in a cubicle house, lying behaviour was prevented for 3 h each morning by enclosing the animals on the slatted floor of the feeding area. Lying time of cows was recorded during the 10 h following deprivation. The 3 h of lying deprivation resulted in a recovery rate of almost 50% within the observation period. When cows were also deprived of food during the lying-deprivation period, the recovery rate of lying did not alter. However, when feeding alone was prevented, the increased feeding tendency did decrease lying time in the subsequent hour. It is concluded that cows aim to achieve a rather fixed amount of lying, and that their well-being must seriously be impaired when lying time is restricted for several hours.
